Answers

There are 30 adults in the swimming pool.

The ratio is a quantitative approach that shows the relation between two proportions.

From the given relation, the ratio of of the children to adults = 8 : 3

The total number of the ratio = 8 + 3 = 11

Given that there are 110 people in the population.

The number of adults that are there will be:

From a box of 120 mangoes, Brent sold 60%. How many mangoes were left?

Answers

Given:-

From a box of 120 mangoes, Brent sold 60%.

To Find :-

How many mangoes are left .

Solution :-

According to the question, box has 120 mangoes . The number of mangoes he sold will be ,

[tex]\longrightarrow[/tex] n(sold) = 60% of 120

[tex]\longrightarrow[/tex] n(sold) = 60/100 × 120

[tex]\longrightarrow[/tex] n(sold) = 3/5 × 120

[tex]\longrightarrow[/tex] n(sold) = 72

Hence the number of mangoes left will be ,

[tex]\longrightarrow[/tex] n(left) = 120 - 72

[tex]\longrightarrow[/tex] n(left) = 48

Hence the number of mangoes left is 48.

Answer:

I believe it's (2d - 1) • (d + 2)

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant   2 • -2 = -4

Step-2 : Find two factors of  -4  whose sum equals the coefficient of the middle term, which is   3 .

     -4    +    1    =    -3

     -2    +    2    =    0

     -1    +    4    =    3    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -1  and  4

                    2d2 - 1d + 4d - 2

Step-4 : Add up the first 2 terms, pulling out like factors :

                   d • (2d-1)

             Add up the last 2 terms, pulling out common factors :

                   2 • (2d-1)

Step-5 : Add up the four terms of step 4 :

Since the Perimeter is the total distance around a figure, to find the Perimeter of a Parallelogram, we calculate the sum of all sides.

Therefore,

P=2(L•W), where P=perimeter, L=length and W=width

Length=7z+3 and Width=3z+5

• Substitute the variables in:

P=2((7z+3)+(3z+5))

• Distributive Property occurs

P=(14z+6)+(6z+10)

• Adding Like Terms

P=20z+16 or 20z+16 is the answer

Two side of a triangle are 26 and 27, while the height to the third side is 25. Find the area of the triangle.

Answers

Based on the information given, the area of the triangle is 291.85.

From the information given,

A = 26

A = 26B = 27

A = 26B = 27C = 25

Firstly, we'll add the sides given and divide them by 2. This will be:

S = (26 + 27 + 25) / 2

S = 78/2

S = 39

Then we will use the formula:

= s(s - a)(s - b)(s - c)

= 39(39 - 26)(39 - 27)(39 - 25)

= 39(13 × 12 × 14)

= 85176

Lastly, we'll find the square root of the value gotten. This will be:

= ✓85176

= 291.85.

Therefore, the area is 291.85.
